pianodraad
Pianodraad, also known as piano wire, is a high-carbon steel wire used primarily for the strings of pianos and other stringed instruments. It is known for its high tensile strength and elasticity, which are crucial for producing clear and sustained musical tones. The manufacturing process involves drawing steel rods through a series of progressively smaller dies to achieve the desired diameter and strength. The specific alloy composition and heat treatment are carefully controlled to optimize its acoustic properties.
The tension of pianodraad strings is a significant factor in the piano's sound and tuning stability. Thicker
